Long-distance identity-certifying system, terminal, servo and method

Abstract

The system comprises: a terminal with the human-face image detecting function and the voice data acquiring function, a communication network and a personal identification server. Wherein, the terminal with the human-face image detecting function and the voice data acquiring function embeds the acquired voice data into the detected human-face image, and sends the human-face image embedded with the voice data to the personal identification server; the identification authentication server separates the voice data from the human-face image, and respectively authenticate the human-face image and the voice data, and then combines them; the authentication result is sent to the terminal.

Description

technical field [0001] The invention relates to the technology of identity authentication in communication network, in particular to a system, terminal, server and method of remote identity authentication in communication network. Background technique [0002] With the rapid development of communication networks, various services are also increasing. How to carry out remote identity authentication in communication networks is becoming more and more important. Remote identity authentication has become a prerequisite and an important part of network service providers to provide various services. The traditional remote identity authentication adopts the method of text password, that is, the terminal sends the text password to the authentication server of the communication network for authentication. This method not only requires the user to remember various cumbersome text passwords, but also the text passwords are easy to be lost and stolen. [0003] In order to make the proce...

Problems solved by technology

[0006] However, there are disadvantages in this remote identity authentication using face authentication: First, because the current best single-mode biometric recognition system based only on faces is still facing the recognition rate in a complex environment. The problem is not high, this kind of remote identity authentication is based on the mobile environment of the wireless communication network, so there is also the problem of low recognition rate; second, the digital watermark embedded in the detected face image is only used to judge people The integrity and correctness of the face image will not affect the subsequent face image recognition, but if the digital watermark adopts a general encryption method, the key is agreed between the terminal and the server. If the face image is intercepted by others and the digital watermark is decrypted, The possibility of cracking is relatively high. After cracking the digital watermark, the face image can be obtained and the decrypted key will re-encrypt the digital watermark on the face image and then pretend to be authenticated on the server side, which makes the security of remote identity authentication not high.
